Oregano

Oregano (オレガノ, Oregano) is a "Medical Specialist Angeloid". Oregano tagged along with Sugata when he was returning from a "Dive Game", and managed to follow him back to Earth.

Appearance
Oregano has bright purple hair and green eyes. She bears a striking resemblance to Ikaros, which in turn, makes Tomoki Sakurai nickname her Miniros. She originally wore a regular cleaning uniform for Angeloids, but when she came to earth and started staying with Satsukitane Mikako, she started wearing a regular yukata.

Personality
Oregano puts on a facade of innocence and cluelessness,or split personality, much like the personality of Ikaros, which prompts Tomoki to coin the nickname "Miniros". In front of Tomoki and most others, Oregano subjects Nymph to various kinds of torture just as her master does when she's alone, even going as far as to drop a number of grenades after trapping her in a cell (which subsequently do explode on her) while making it look like Nymph was the one bullying her. Thus at present, she is not on good terms with Nymph while appearing as a quiet and innocent Angeloid to all others. She appears to favor Tomoki, and seems to respect Ikaros. It was later revealed that her unfriendly act toward Nymph is because back when she was in Synapse, Nymph will once a while go to their town and sing a song to release her sadness; however her singing skills are so bad that it causes a lot of Oregano's companions to become comatose. Nymph even used her hacking abilities to make the Oregano Angeloids to kneel on the floor and listen to her singing. They even tried to escape out of town when Nymph visited.

There is one theory on how and why Oregano gained a split personality, though yet unconfirmed. It could have something to do with Mikako Satsukitane, because she was the one who installed the speech functions, and possibly messed around with behavioral functions, developing a split personality where she is aggressive towards Nymph. Oregano has the same battle characteristics as Mikako, using deadly firearms as her weapon of choice and ridicules her opponent with their weaknesses. This could be seen when Oregano insults Nymph, saying she has a flat chest, and when she battles Nymph in the "Angeloid World Martial Arts Competition" when she defeats Nymph using various firearms.

History
Oregano was in Synapse in the residential district until she accidentally followed Sugata to earth.

Nymph
Oregano hates Nymph because in Synapse, Nymph would always force the Oregano Angeloids to listen to her sing.

Ikaros
Oregano's attitude seems to be in sync with Ikaros. They are both on good terms.
